Supreme Court Leaves the Clean Water Act Intact

Victory: Court decision leaves in place vital protections for the nation’s oceans, rivers, lakes

This decision is a huge victory for clean water. The Supreme Court has rejected the Trump administration’s effort to blow a big hole in the Clean Water Act’s protections for rivers, lakes, and oceans.

Washington, D.C. — Today the Supreme Court issued its opinion in County of Maui v. Hawaiʻi Wildlife Fund siding with clean water advocates that point source discharges to navigable waters through groundwater are regulated under the Clean Water Act. 

The following is a statement from David Henkin, Earthjustice attorney who argued the case defending clean water:

“This decision is a huge victory for clean water. The Supreme Court has rejected the Trump administration’s effort to blow a big hole in the Clean Water Act’s protections for rivers, lakes, and oceans.”

Attorney David Henkin, based in Earthjustice's Honolulu office, has worked for more than two decades to defend Hawaiʻi's flora and fauna. He defended our nation's clean water at the U.S. Supreme Court.

“We will have to return to the lower court to confirm this, but we fully expect that Maui County’s sewage plant will be required to get a Clean Water Act permit as a result of the Court’s decision today. That permit will require the County to protect the ocean from sewage discharges in a way it has refused to do to date.

“We are glad the Court has recognized the importance of protecting clean water for all Americans.”

The court held that the Clean Water Act “require[s] a permit if the addition of the pollutants through groundwater is the functional equivalent of a direct discharge from the point source into navigable waters.” In other words, the Clean Water Act prohibits unpermitted discharge of pollution “into navigable waters, or when the discharge reaches the same result through roughly similar means.” In doing so, the Court rejected the Trump administration’s polluter-friendly position in the clearest of terms: “We do not see how Congress could have intended to create such a large and obvious loophole in one of the key regulatory innovations of the Clean Water Act.”

The opinion was written by Justice Breyer with a vote of 6-3; with Chief Justice Roberts joining the opinion, along with Ginsburg, Sotomayor, Kagan, and Kavanaugh.
